Tie line power control of HVDC transmission to damp frequency fluctuation of power system with large scale wind farm integrated

Abstract

In this paper, effect of tie line power control of two area power system connected through VSC-HVDC line on damping load frequency deviation is investigated. New control scheme of the VSC-HVDC to provide frequency regulation is proposed. The control strategy is useful for connecting a power system with high penetration of wind farm to other power system. The study has been performed by simulation analysis using PSCAD/EMTDC, and the dynamic performance of the VSC-HVDC with the proposed control is demonstrated. Simulation results shows that proposed controller can damp frequency fluctuation effectively.
